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