This polychoron can be obtained as the convex hull of a q-hex, a unit ico, an a-rit, and a b-tes, where a = [4+sqrt(2)]/7 = 0.773459 and b = [2+3 sqrt(2)]/7 = 0.891806. (All of those sizes so far just describe pseudo edges only.) Edges then occur between the first two with size c = sqrt[2-sqrt(2)] = 0.765367, between second and third with size d = sqrt[20-2 sqrt(2)]/7 = 0.591980, and between the last two with size e = sqrt[7+3 sqrt(2)]/7 = 0.479001. Faces all are deltoidal tetragons with sides c (red) and d (blue) or with sides d (blue) and e (green), while cells all are identical 3-fold axial deltoidal hexahedra (shown on the right) and have 3 edges of size c, 6 of size d, and 3 of size e.
