Presentation

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

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

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