I am looking for a comprehensive list of the IOC values of any or all classical ciphers. I can't find a list, only pieces. Each cipher has an average IOC value, and I was wondering if there was a comprehensive list of these values for every classical cipher available. Can anyone share a list of these IOC values?

    $\begingroup$ the IOC is obtained from a ciphertext corresponding to some given concrete plaintext. Under a statistical model for the natural language (English, say) the plaintext belongs to, it should be close to the collision probability $\sum_{x\in \{A,B,\ldots,Z\}} p_x^2$ of the natural language. So, what are you exactly asking? $\endgroup$ – kodlu Oct 11 '20 at 0:14
