Presentation

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

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

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