Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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