Root + Minor Third + Diminished Fifth + Major Seventh = ???

I know

Root + Minor Third + Diminished Fifth + Diminished Seventh (Major Sixth)= Full Diminished
Root + Minor Third + Diminished Fifth + Minor Seventh = Half Diminished

But

Root + Minor Third + Diminished Fifth + Major Seventh = ???

It's a "slash chord", a triad over a non-triadic bass note. Eg, if that bass note is C, you've got C - Eb - Gb - B...which enharmonically becomes C - D# - F# - B, or a B major triad over a C bass note. Written B/C.

Brilliant thats what I thought but I wasn't sure and the fact that you said that guarantees it to me. Thanks.
