Presentation

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

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

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