Presentation

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

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

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