Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

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

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((8,10)(11,12,14,15)(13,17,18,16)(19,20,22,23)(21,25,26,24), (4,6)(8,10)(12,15)(16,17)(19,20,22,23)(21,25,26,24), (3,4,5,6)(7,8,9,10)(12,15)(13,18)(20,23)(24,25), (11,12)(13,16)(14,15)(17,18)(19,21)(20,24)(22,26)(23,25), (3,4)(5,6)(11,13)(12,16)(14,18)(15,17)(19,20)(21,24)(22,23)(25,26), (1,2));
