Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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