Old description:
New description:
Gives a minimal implementation of the `A_oo` Cartan type:
{{{#!sage
sage: CartanType(['A',oo])
['A', oo]
sage: CartanType(['A',oo]).is_irreducible()
True
sage: CartanType(['A',oo]).is_simply_laced()
True
sage: print(CartanType(['A', oo]).ascii_art())
...---O---O---O---O---O---O---O---...
-3 -2 -1 0 1 2 3
}}}
In addition, the ficket fixes the following error:
{{{#!sage
sage: CartanType(['A',-1])
File "<string>", line unknown
^
SyntaxError: unexpected EOF while parsing
}}}
