Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 26 points:

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