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