Presentation

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

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

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