Presentation

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

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

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

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