Presentation

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

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

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