Causative passive form vs. Passive causative form: Both are grammatically possible, but is there a citation to prefer one over the other?


The "causative passive" form is very well documented. It's easily made
possible because the a causative verb is a valid ichidan verb, and therefore
compatible with the passive conjugation.

However, in the resources I have on-hand, there is nothing to suggest the
inverse is commutative. To be specific, does a "passive causative" verb have a
meaning equal to that of the "causative passive"?

Furthermore, is the "passive causative" conjugation ordering even used? Or is
it unconventional?

## Hypothesis

  1. ❌ The conjugations have a commutative property ("causative passive" is semantically identical to the "passive causative"); 
    * **❌ This hypothesis is disproved on the basis that conjugation ordering matters. Thank you, @naruto !**
    * **❌ Furthermore, the final component/conjugation suffix is the main function of the verb. Thank you, @aguijonazo !**
  2. ❌ The "causative passive" is euphonically preferred (「聞かせられる」 is easier to say and more pleasing to hear than ~~「聞かれらせる」~~ 「聞かれさせる」); 
    * Therefore the "passive causative" is unconventional and never used.
    * **❌ This hypothesis is disproved on the basis of being dependent on the first, disproven, hypothesis. This hypothesis doesn't have a leg to stand on! Thank you, @Jun Sato !**

If my speculations hold true, then I'm seeking a citation to support these
claims (which is actually the aim of this question).

### Edit:

There was a typo (ら instead of さ), which confused some of the people who tried
to help in the answers.




There is no "passive-causative form" as you suggest in Japanese. Japanese verb
conjugations can be "stacked", but not all combinations are possible. There is
a correct order you have to respect. If you want the causative-passive meaning
described in your textbook, you must always use させられる, not られさせる.

  * つまらない音楽を聞かせられた。(or ～を聞かされた)  
I was made to listen to boring music. (i.e., They made me listen to boring
music.)

  * 私は泣かせられた。(or 泣かされた)  
I was made to cry.

Sometimes, there are situations where you want to "make someone/something be
in some passive state". Even in such cases, "passive-causative" られさせる is not a
thing. Instead, you need to say ～れるようにする, ～れろと言う/命じる, etc.

  * 音楽が聞かれるようにした。  
I let the music be heard.  
(×聞かれさせた is incorrect)

  * 彼に殴られろと命じた。  
I told him that he must be beaten.  
(×殴られさせた is incorrect)
