Presentation

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

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

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

GAP

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

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