Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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

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

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