I'd like to display this font of blackboard bold characters:

enter image description here

Is this included in the amsmath package? If so, it appears to not respond to \Bbb or \mathbb. So, do I need another package or am I using the wrong functions? If the former, which package will display the above font? I saw that the package {bbold} uses a different font than the one I want.

  • @DavidCarlisle How is amsfonts different from amssymb? I did what Sebastiano's answer said and it worked, but I assume amsfont has perhaps even more symbols or more fonts?
