Presentation

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

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

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