লিখলাম । কিন্তু, এমনিতেই দেখা যেত । যখন মনে হবে কিছু কাটা পরেছে Ctrl টিপে - টিপবা । অর্থাৎ ফন্ট ছোট করবা । তাহলেই দেখতে পারবা । চাইলে দেখে নিতে পার ।

I think it was slip of typing.
Because there are total $40$ numbers using
Principle pf inclusion-exclusion.But in the list there are 38 numbers.So,if we add $9$ and $69$ in the list,The list will be completed.
