other/another

Hi

I know that these two (other, another) are not the same, however, both of them can mean "different" so how about such a sentence "I haven't got other idea"/ I haven't got another idea" Do they mean the same in this case?

thank you

other by itself would need a plural noun after it.

another idea, the other idea, other ideas, the other ideas
another ticket, the other ticket, other tickets, the other tickets
