Presentation

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

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

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