79 <p>Returns an array containing references to independent cyclic paths identified during cycles
80 detection. In scalar text, number of cycles is returned.</p>
81 <p>A set of independent cycles identified during cycles detection doesn't correspond to the basis set of
82 rings or smallest set of smallest rings (SSSR) [ Refs 29-30 ]; instead, set of cycles indentified
83 as independent cycles simply correpond to cycles which contain no other cycle as their
84 subcycles and can't be described as a linear combination of smaller cycles. And it also happens
85 to contain all the rings in basis set of rings and SSSR. In other words, it's a superset of a basis set
86 of cycles and SSSR. For example, six four membered cycles are indentified for cubane, which is one
87 more than the basis set of cycles.</p>
