3.7.8. All different

Denotes that we have one or several cliques of disequalities or that a constraint is a variation of the 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 constraint. Variations may be related to relaxation (see, e.g., the 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚎𝚡𝚌𝚎𝚙𝚝_0, 𝚜𝚘𝚏𝚝_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚌𝚝𝚛, and 𝚜𝚘𝚏𝚝_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚟𝚊𝚛 constraints), or to specialisation (see, e.g., the 𝚜𝚢𝚖𝚖𝚎𝚝𝚛𝚒𝚌_𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 constraint), of the 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝 constraint. Variations may also result from an extension of the notion of disequality (see, e.g., the 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚒𝚗𝚝𝚎𝚛𝚟𝚊𝚕, 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚖𝚘𝚍𝚞𝚕𝚘, 𝚊𝚕𝚕𝚍𝚒𝚏𝚏𝚎𝚛𝚎𝚗𝚝_𝚙𝚊𝚛𝚝𝚒𝚝𝚒𝚘𝚗 and 𝚐𝚘𝚕𝚘𝚖𝚋 constraints).
