# Strange result for Jordan_form()

```
M = matrix([[4,-1,6],[2,1,6],[2,-1,8]])
MM=M.jordan_form(transformation=true)
show(MM)
show(MM[0])
show(MM[1])
show(MM[1]^(-1))
show(MM[1]^(-1)*MM[1])
show(MM[1]^(-1)*MM[0]*MM[1])
show(bool(MM[1]^(-1)*MM[0]*MM[1]==M))
```

According to the documentation and what I know of Jordan decomposition the last line should be True. No ?
