Presentation

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

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

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

GAP

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

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