Presentation

minimal degree	μ(G) = 26
transitive degree	μ_t(G) = 128

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

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

GAP

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

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