Kashf Alarqam Alymnyh Aljdydh 78 -

It seems you are referring to a text titled (كشف الأرقام اليمنية الجديدة) — possibly with the number 78 indicating a section, edition, or manuscript folio. However, this is not a widely known standard work in Islamic or Arabic literature. It may be a rare manuscript, a modern esoteric publication, or a local text from Yemeni or Sufi contexts.
