Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

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

GAP

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