Is there a reference for arpeggios of diminished triad?

I've not seen one - but that doesn't mean one doesn't exist...

When you say triads you mean three notes only (?), in which case I would finger them as follows:

Hope that helps?

Is there a reference for arpeggios of diminished triad?  For example, A in the key of BbMajor.

Even in my wonderful ABRSM scale manual, arps and broken chords are listed in major, minor, and augmented triads, but not diminished.  This surprises me since they come up whenever you do a whole key's worth of arpeggios.  For the keys I am working on (C, G, F) 1235 seems to work fine, but maybe not for keys with more sharps / flats??  Likely there is something in the tradition that makes total sense that I am missing....

Tx!
