Presentation

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

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

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

GAP

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

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