Answer 1

public Group createSharepointGroup(string Name, string description)
    {
        try
        {
            GroupCreationInformation groupInfo = new GroupCreationInformation();
            groupInfo.Description = description;
            groupInfo.Title = Name;


            Group group = currentWeb.SiteGroups.Add(groupInfo);

            clientContext.Load(group);
            clientContext.ExecuteQuery();

            return group;

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.InnerException.ToString());
            return null;
        }

    }

The answer depends on what platform you want to do this programatically with. I'm assuming you're using PowerShell, in which case your best bet is the Add-SPOUser cmdlet, which "Adds an existing Office 365 user or an Office 365 security group to a SharePoint group."

The example below assumes you're using PowerShell:

$SecGroupName = "TestSecurityGroup"        # The security group DisplayName
$SPOGroupName = "TestSharePointGroup"      # The SharePoint Online group

# Get the SharePoint site
$SPOSite = Get-SPOSite "https://contoso.sharepoint.com"

# Add the security group as a member of the SharePoint Online group
Add-SPOUser -Site $SPOSite -LoginName $SecGroupName -Group $SPOGroupName

Some links you might find usefull:

• Set up the SharePoint Online Management Shell Windows PowerShell environment
• Use Windows PowerShell cmdlets to administer users and groups in SharePoint Online
• Manage Windows Azure AD using Windows PowerShell
• Manage Azure AD group and role membership

(Note that users and groups in Office 365 are actually Azure Active Directory users and security groups, which is why I provide links to the Azure AD PowerShell cmdlets.)
