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