identicality
State of being indistinguishable
Identicality is the state of being identical—complete sameness in every relevant respect.
The word is formal and somewhat awkward, typically appearing in technical or philosophical contexts where *identity* won't do: The identicality of the twins' DNA confirmed they were monozygotic.
Most speakers prefer *identicalness* or simply rephrase.
