Presentation

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

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

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