Presentation

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

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

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