Presentation

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

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

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