# Is a single 256 bits hash table in which the digests are from mixed cryptographic hashing algorithms still considered collision resistant?

Consider a single hash table containing digests from about 10 different 256 bits cryptographic hashing functions, like SHA256, SHA3, KECCACK256, BLAKE2, BLAKE3, etc...

Is such table still considered collision resistant?

I am inclined to think so, but I might be missing something.

The restriction to standard hashes is necessary to repel hashes specially crafted to allow a collision; like e.g. $$H(M)=\operatorname{RIPEMD-256}(M)\oplus\bigl(\operatorname{RIPEMD-256}(\mathtt{‘foo’})\oplus\operatorname{SHA-256}(\mathtt{‘bar’})\bigr)$$, which is such that $$H(\mathtt{‘foo’})=\operatorname{SHA-256}(\mathtt{‘bar’})$$.
