Presentation

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

A minimal faithful permutation representation — 8 generators on 26 points:

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

GAP

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

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