Presentation

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

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

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