Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 20 points:

(10,11)(13,14,15,16)(17,18,19,20);(1,2,3,4)(5,6,8,7)(13,14)(15,16);(2,4)(6,7)(14,16);(6,7)(9,10,12,11)(13,14)(15,16)(17,18)(19,20);(1,2)(3,4)(5,7,8,6)(9,11,12,10)(13,14)(15,16)

Polycyclic presentation:

2^10|a^2=f,b^2=fi,d^2=g,e^2=h,b^a=bfj,c^a=cfj,c^b=cij,d^a=dfg,d^b=dgh,d^c=dfj,e^a=efgj,e^b=efghi,e^c=eij,e^d=egh

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
