Presentation

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

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

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

GAP

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

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