Presentation

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

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

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

GAP

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

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