Presentation

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

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

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

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

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