Presentation

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

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

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