Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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