Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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

GAP

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

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