Docstring:
A triangular sandpile. Each nonsink vertex has out-degree six.
The vertices on the boundary of the triangle are connected to the
sink.
INPUT:
"n" -- integer
OUTPUT:
Sandpile
EXAMPLES:
sage: from sage.sandpiles.sandpile import triangle_sandpile
sage: T = triangle_sandpile(5)
sage: T.group_order()

EXAMPLES:
sage: from sage.misc.lazy_import import LazyImport
sage: my_integer = LazyImport('sage.rings.all', 'Integer')
sage: my_integer(4)

sage: my_isprime(5)
True
sage: my_isprime(55)
False
Call docstring:
Calling self calls the wrapped object.
