Presentation

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

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

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

GAP

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

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