Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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