Presentation

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

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

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

GAP

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

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