Presentation

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

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

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