why I get huge number in H-representation in sage?

edit

I have a set of vertices and I want to find a H-representation of them. I used sage to do that but I got weird number in the inequalities! here is my code:

vert2 = [[1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4,1,0,3,0,1],[1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4,1,0,3,0],[0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4,1,0,3],[3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4,1,0],[0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4,1],[1,0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3,4],[4,1,0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2,3],[3,4,1,0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3,2],[2,3,4,1,0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4,3],[3,2,3,4,1,0,3,0,1,1,2,3,4,2,3,6,0,0,7,6,8,0,1,2,3,4,5,6,7,4],

p2=Polyhedron(vertices = vert2)
p2
p2.Hrepresentation()

And here is the part of my answer:
