Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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