Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 2 generators on 32 points:

(1,2,5,8,7,11,15,10)(3,6,12,16,9,4,13,14)(17,18,20,25,22,26,21,31)(19,27,29,32,30,23,28,24);(1,3,6,8,5,13,16,2,7,9,4,10,15,12,14,11)(18,23,26,27)(19,28)(20,21)(24,25,32,31)(29,30)

Polycyclic presentation:
