Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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