Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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