karena istilah ilmiah (ilmu matematik pula) yang seharusnya bisa dipahami secara global, saya usulkan diserap saja menjadi representasi dan memang sudah diakui di KBBI (makna no. 3). Selain juga baik untuk penerjemahan balik.

representasi 1 perbuatan mewakili; 2. kedaaan diwakili; 3 apa yang mewakili; perwakilan

Maknanya mengarah ke makna no 3. di KBBI bisa di pahami dari pertanyaan di bawah:

What kind of primes is represented by the
binary quadratic form x2+xy-y2?
(x and y are positive coprime integers)
It is well-known that x2+y2 represented primes
of the form 4n+1 . How can we proceed to calculate
x and y when we are given a prime of the form
4n+1 ?
For example, it is given that 262657 is a prime,
how can we calculate x and y such that
x2+y2=262657 ?
Obviously, x and y should be coprime integers.
Anyone got an idea? Please Help.

Mungkin versi lengkapnnya

our representation ---> representasi yang kita cari.
