The special edge with 3 incident mibdies of this polychoron (each being adjoined with their special wedge edge) also allows for a 5-fold counterpart: xfoxo oxfox5ooofx&#xt. (A 4-fold version does not exist, so.)
Any mibdi here allows for an independant augmentation by an appropriate pyramid. The corresponding triaugmentation then is xofox ooxfo3oxoox&#xt.
In the above lace city the lower diagonal from the left b via the medial c towards the right d provides a teddi sectioning facet. If dissected at that hyperplane the polychoron falls into {3}||teddi (at the lower left) and tetu (at the upper right).

xfox oxfo3ooox&#xt → height(1,2) = sqrt[(7+3 sqrt(5))/24] = 0.755761 height(2,3) = sqrt[(3+sqrt(5))/24] = 0.467086 height(3,4) = sqrt(3)/6 = 1/sqrt(12) = 0.288675 o... o...3o... | 2 * * * | 1 3 0 0 0 0 0 0 | 3 3 0 0 0 0 0 0 0 0 | 3 1 0 0 0 0 a .o.. .o..3.o.. | * 6 * * | 0 1 2 1 2 0 0 0 | 1 2 1 2 2 1 0 0 0 0 | 2 1 1 1 0 0 b ..o. ..o.3..o. | * * 3 * | 0 0 0 2 0 4 0 0 | 1 0 0 4 0 0 2 2 0 0 | 2 0 0 2 1 0 c ...o ...o3...o | * * * 6 | 0 0 0 0 2 2 1 2 | 0 0 0 2 1 2 2 2 2 1 | 1 0 1 2 2 1 d -------------------+---------+-------------------+----------------------+------------ x... .... .... | 2 0 0 0 | 1 * * * * * * * | 3 0 0 0 0 0 0 0 0 0 | 3 0 0 0 0 0 oo.. oo..3oo..&#x | 1 1 0 0 | * 6 * * * * * * | 1 2 0 0 0 0 0 0 0 0 | 2 1 0 0 0 0 .... .x.. .... | 0 2 0 0 | * * 6 * * * * * | 0 1 1 0 1 0 0 0 0 0 | 1 1 1 0 0 0 .oo. .oo.3.oo.&#x | 0 1 1 0 | * * * 6 * * * * | 1 0 0 2 0 0 0 0 0 0 | 2 0 0 1 0 0 .o.o .o.o3.o.o&#x | 0 1 0 1 | * * * * 12 * * * | 0 0 0 1 1 1 0 0 0 0 | 1 0 1 1 0 0 ..oo ..oo3..oo&#x | 0 0 1 1 | * * * * * 12 * * | 0 0 0 1 0 0 1 1 0 0 | 1 0 0 1 1 0 ...x .... .... | 0 0 0 2 | * * * * * * 3 * | 0 0 0 0 0 0 2 0 2 0 | 1 0 0 0 2 1 .... .... ...x | 0 0 0 2 | * * * * * * * 6 | 0 0 0 0 0 1 0 1 1 1 | 0 0 1 1 1 1 -------------------+---------+-------------------+----------------------+------------ xfo. .... ....&#xt | 2 2 1 0 | 1 2 0 2 0 0 0 0 | 3 * * * * * * * * * | 2 0 0 0 0 0 .... ox.. ....&#x | 1 2 0 0 | 0 2 1 0 0 0 0 0 | * 6 * * * * * * * * | 1 1 0 0 0 0 .... .x..3.o.. | 0 3 0 0 | 0 0 3 0 0 0 0 0 | * * 2 * * * * * * * | 0 1 1 0 0 0 .ooo .ooo3.ooo&#x | 0 1 1 1 | 0 0 0 1 1 1 0 0 | * * * 12 * * * * * * | 1 0 0 1 0 0 .... .x.o ....&#x | 0 2 0 1 | 0 0 1 0 2 0 0 0 | * * * * 6 * * * * * | 1 0 1 0 0 0 .... .... .o.x&#x | 0 1 0 2 | 0 0 0 0 2 0 0 1 | * * * * * 6 * * * * | 0 0 1 1 0 0 ..ox .... ....&#x | 0 0 1 2 | 0 0 0 0 0 2 1 0 | * * * * * * 6 * * * | 1 0 0 0 1 0 .... .... ..ox&#x | 0 0 1 2 | 0 0 0 0 0 2 0 1 | * * * * * * * 6 * * | 0 0 0 1 1 0 ...x .... ...x | 0 0 0 4 | 0 0 0 0 0 0 2 2 | * * * * * * * * 3 * | 0 0 0 0 1 1 .... ...o3...x | 0 0 0 3 | 0 0 0 0 0 0 0 3 | * * * * * * * * * 2 | 0 0 1 0 0 1 -------------------+---------+-------------------+----------------------+------------ xfox oxfo ....&#xt ♦ 2 4 2 2 | 1 4 2 4 4 4 1 0 | 2 2 0 4 2 0 2 0 0 0 | 3 * * * * * .... ox..3oo..&#x ♦ 1 3 0 0 | 0 3 3 0 0 0 0 0 | 0 3 1 0 0 0 0 0 0 0 | * 2 * * * * .... .x.o3.o.x&#x ♦ 0 3 0 3 | 0 0 3 0 6 0 0 3 | 0 0 1 0 3 3 0 0 0 1 | * * 2 * * * .... .... .oox&#x ♦ 0 1 1 2 | 0 0 0 1 2 2 0 1 | 0 0 0 2 0 1 0 1 0 0 | * * * 6 * * ..ox .... ..ox&#x ♦ 0 0 1 4 | 0 0 0 0 0 4 2 2 | 0 0 0 0 0 0 2 2 1 0 | * * * * 3 * ...x ...o3...x ♦ 0 0 0 6 | 0 0 0 0 0 0 3 6 | 0 0 0 0 0 0 0 0 3 2 | * * * * * 1
