Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 28 points:

(2,3)(5,6)(7,11)(8,10)(9,12)(13,14)(15,16)(17,21)(18,22)(19,23)(20,27)(24,26)(25,28);(1,2)(3,4)(5,6)(7,11)(8,10)(9,12)(13,15)(14,16)(17,24)(18,20)(19,25)(21,26)(22,27)(23,28);(1,3,4,2)(6,10)(7,8)(11,12)(13,16)(14,20)(15,21)(17,26)(18,27)(19,28)(22,25)(23,24);(5,7,9,8)(6,11,12,10)(13,17,19,18)(14,21,23,22)(15,24,25,20)(16,26,28,27)
