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

Polycyclic presentation:

2^9|a^2=g,b^2=f,c^2=fh,g^2=i,b^a=bd,c^a=ce,d^a=dh,c^b=cf,g^b=gh
