Presentation

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

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

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

GAP

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