Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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