Presentation

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

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

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

GAP

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

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