-----------------------+----------------------------------------------------
The class sage.combinat.root_system.type_reducible.CartanType
is missing an is_crystalographic and is_simply_laced
{{{
sage: R = CartanType("D4xA5")
sage: R.is_crystalographic()
sage: R.is_simply_laced()
}}}
These both give False which is incorrect.
