Presentation

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

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

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