Gistic occurs in 4 different forms depending on whether the vertices (coincident by 2) will be counted separately (type A,C), or will be identified (type B,D), and whether the components are being considered to be teses (type A,B), or to be gicoes (type C,D).

As the snub of tes is nothing but hex, accordingly the snub of gico will be sistic.
