Presentation

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

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

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