Presentation

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

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

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

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

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