From a mathematical point of view, the genetic code is a surjective mapping between the set of the 64 possible threebase codons and the set of 21 elements composed of the 20 amino acids plus the Stop signal.

In analogy with the genetic code, nonpower integernumber representations are also surjective mappings between sets of different cardinality and, as such, also redundant.

In Math Man's terms: you can write an injective relationship, but not a surjective one.

AlgL and morphisms the algebraic homomorphisms are surjective homomorphisms.

But the Zariski topology is not metrizable … is a surjection of sheaves (exercise!), yet the map on global sections is not surjective.

Quotient topology: The finest topology on the image set that makes a surjective map from a topological space continuous.

However, when you tap on surjective for more information, you are given the correct definition.

The definition they provide for surjective is actually the definition for injective.
