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